其實(shí)變頻器也一樣的。溫度升高時(shí)，由于半導(dǎo)體對(duì)溫度的敏感性，逆變管的開(kāi)通時(shí)間和關(guān)斷時(shí)間，以及由延遲電路產(chǎn)生的等待時(shí)間，都將發(fā)生變化，并且具有比較準(zhǔn)確的變化規(guī)律。當(dāng)溫度一旦超過(guò)某一限值時(shí)，將引起“等待時(shí)間”的不足，使逆變電路的輸出波形出現(xiàn)“毛刺”，并終導(dǎo)致逆變管因直通而損壞。但就多數(shù)設(shè)備而言，其破壞作用常常是比較緩慢的，受破壞時(shí)的溫度通常是不很準(zhǔn)確的，而唯獨(dú)在變頻器逆變電路中，溫度一超過(guò)某一限值，會(huì)立即導(dǎo)致逆變管的損壞，并且該溫度限值往往十分。安裝環(huán)境不準(zhǔn)確變頻器是一臺(tái)全電力半導(dǎo)體設(shè)備，所以，它對(duì)周?chē)h(huán)境的要求也和其他電力半導(dǎo)體設(shè)備相同。環(huán)境濕度：相對(duì)濕度不超過(guò)90%（無(wú)結(jié)露現(xiàn)象）其它條件：在變頻器的安裝位置應(yīng)無(wú)直射陽(yáng)光、無(wú)腐蝕性氣體及易燃?xì)怏w、塵埃少、海拔低于1000m等。

它的二次回路始終是閉合的，因此測(cè)量?jī)x表和保護(hù)回路串聯(lián)線圈的阻抗很小，電流互感器的工作狀態(tài)接近短路。工作原理編輯在發(fā)電、變電、輸電、配電和用電的線路中電流大小懸殊，從幾安到幾萬(wàn)安都有。為便于測(cè)量、保護(hù)和控制需要轉(zhuǎn)換為比較統(tǒng)一的電流，另外線路上的電壓一般都比較高如直接測(cè)量是非常危險(xiǎn)的。電流互感器就起到電流變換和電氣隔離作用[1]。對(duì)于指針式的電流表，電流互感器的二次電流大多數(shù)是安培級(jí)的（如5A等）。對(duì)于數(shù)字化儀表，采樣的信號(hào)一般為毫安級(jí)（0-5V、4-20mA等）。微型電流互感器二次電流為毫安級(jí)，主要起大互感器與采樣之間的橋梁作用。微型電流互感器也有人稱之為“儀用電流互感器”。（“儀用電流互感器”有一層含義是在實(shí)驗(yàn)室使用的多電流比精密電流互感器。

都會(huì)在二次側(cè)產(chǎn)生數(shù)千伏甚至上萬(wàn)伏的過(guò)電壓。這不僅給二次系統(tǒng)絕緣造成危害，還會(huì)使互感器過(guò)激而燒損，甚至危及運(yùn)行人員的生命。電流互感器電流互感器1次側(cè)只有1到幾匝，導(dǎo)線截面積大，串入被測(cè)電路。2次側(cè)匝數(shù)多，導(dǎo)線細(xì)，與阻抗較小的儀表(電流表/功率表的電流線圈）構(gòu)成閉路。電流互感器的運(yùn)行情況相當(dāng)于2次側(cè)短路的變壓器，忽略勵(lì)磁電流，安匝數(shù)相等I1N1=I2N2電流互感器一次繞組電流I1與二次繞組I2的電流比，叫實(shí)際電流比I1/I2=N2/N1=k。勵(lì)磁電流是誤差的主要根源。測(cè)量用電流互感器的精度等級(jí)0.2/0.5/1/3,1表示變比誤差不超過(guò)±1%，另外還有0.2S和0.5S級(jí)。保護(hù)用電流互感器保護(hù)用電流互感器分為：1.過(guò)負(fù)荷保護(hù)電流互感器。
